Abstract

The invention discloses a graphene oxide-cerium hydroxide composite material, a preparation method and an application thereof. In this experiment, graphene oxide-ceric hydroxide composites (Ce(OH) 4 / GO) to adsorb and remove Congo red (CR) and phosphate ion (PO) in the solution 4 3‑ ), and the structure of the composite material was characterized by SEM, FT-IR, etc., and the Congo red (CR) and phosphate ion (PO 4 3‑ ) adsorption effect was discussed, and the optimal adsorption conditions were determined as follows: pH 7.0 and 6.0, adsorption time 6 hours, temperature 50°C and 30°C. Congo red and PO were obtained by Langmuir model analysis 4 3‑ The maximum adsorption capacity is 563.67mg / g, 619.63mg / g respectively, and the adsorption effect is remarkable.

Description

【Technical field】 [0001] The invention belongs to the technical field of preparation of water treatment agents, and in particular relates to a graphene oxide-cerium hydroxide composite material, a preparation method and an application thereof. 【Background technique】 [0002] There are many wastewater treatment technologies, such as: flocculation, membrane filtration, solvent extraction, biosorption, chemical precipitation, ion exchange, reverse osmosis, electrocoagulation, sintering, electrolytic precipitation, coagulation and adsorption, etc. Among them, the adsorption method has become a widely used method for removing pollutants due to its advantages of cheap production and simple operation and treatment process. It is very important to design new adsorbents with excellent adsorption capacity. [0003] There are many kinds of adsorbents, which can be mainly divided into three categories: [0004] The first category is more common porous adsorption materials, such as acti...
